摘要：

The Raman-scattering spectra of I-III-VI2 group chalcopyrite semiconductors and their solid solutions were measured. The frequency relationship for the A1 vibrational mode agrees with the simple ratio of the anion atomic weights, although it also depends on the mean atomic weights of the cations. Compositional change of the A1 mode frequency for their solid solutions with anion substitution can be explained by the probability of formation of two pairs of anion atoms.
